Title (EN) OIL PUMP
(FR) POMPE À HUILE
(ZH) 油泵
Abstract:
(EN) An oil pump (100) comprises a pump housing, a pump shaft (5), and a pump rotor assembly (8). The pump housing is capable of forming a pump cavity. The pump cavity comprises a first cavity (80) and a second cavity (90). The pump rotor assembly (8) is provided in the first cavity (80). At least part of the pump shaft (5) is provided in the second cavity (90). The pump rotor assembly (8) comprises a first rotor (81) and a second rotor (82). The first rotor (81) is capable of rotating the second rotor (82), and is fixedly connected to the pump shaft (5). The pump shaft (5) is capable of rotating the first rotor (81). The first rotor (81) comprises a connecting portion (812). A connecting hole (8123) is provided in the connecting portion (812). At least part of the pump shaft (5) is provided in the connecting hole (8123). At least part of the connecting portion (812) engages with at least part of the pump shaft (5). The configuration improves reliability of the connection between the pump shaft (5) and the first rotor (81), thereby facilitating transmission between the pump shaft (5) and the first rotor (81), and simplifying assembly of the pump shaft (5) and the first rotor (81).
(FR) L'invention concerne une pompe à huile (100) comprenant un carter de pompe, un arbre de pompe (5) et un ensemble (8) de rotors de pompe. Le carter de pompe est apte à former une cavité de pompe. La cavité de pompe comprend une première cavité (80) et une seconde cavité (90). L'ensemble (8) de rotors de pompe est disposé dans la première cavité (80). Au moins une partie de l'arbre de pompe (5) est disposée dans la seconde cavité (90). L'ensemble (8) de rotors de pompe comprend un premier rotor (81) et un second rotor (82). Le premier rotor (81) permet d'entraîner en rotation le second rotor (82), et est en prise fixe avec l'arbre de pompe (5). L'arbre de pompe (5) permet d'entraîner en rotation le premier rotor (81). Le premier rotor (81) comprend une partie de prise (812). Un trou de prise (8123) est ménagé dans la partie de prise (812). Au moins une partie de l'arbre de pompe (5) est disposée dans le trou de prise (8123). Au moins une partie de la partie de prise (812) coopère avec au moins une partie de l'arbre de pompe (5). La configuration améliore la fiabilité de la prise entre l'arbre de pompe (5) et le premier rotor (81), facilitant ainsi la transmission entre l'arbre de pompe (5) et le premier rotor (81), et simplifiant l'assemblage de l'arbre de pompe (5) et du premier rotor (81).
(ZH) 一种油泵(100),包括泵外壳、泵轴(5)以及泵转子组件(8),泵外壳能够形成泵内腔,泵内腔包括第一腔(80)和第二腔(90),泵转子组件(8)设置于第一腔(80),至少部分泵轴(5)设置于第二腔(90),泵转子组件(8)包括第一转子(81)和第二转子(82),第一转子(81)能够带动第二转子(82)转动,第一转子(81)与泵轴(5)固定连接,泵轴(5)能够带动第一转子(81)转动,第一转子(81)包括一连接部(812),连接部(812)成形有一连接孔(8123),至少部分泵轴(5)设置于连接孔(8123),至少部分连接部(812)与至少部分泵轴(5)紧配;这样设置一方面有利于提高泵轴(5)与第一转子(81)连接的可靠性,从而有利于泵轴(5)与第一转子(81)之间的传动,另一方面使泵轴(5)与第一转子(81)更容易实现装配。
